    Sand and Gravel Mining Process. Once an aggregate deposit is found, the first step in extracting the sand and gravel is to clear the surface of vegetation and topsoil and dig a pit. Since the water table is so close to the surface in Nebraska, the pit fills with water and forms a lake. A dredge is placed in the lake to extract the aggregate from the pit; the material is then carried by running
